To find the GCF of a group of numbers, you can list the factors of each number:
39: 1, 3, 13, 39
45: 1, 3, 5, 9, 15, 45
75: 1, 3, 5, 15, 25, 75
92, 1, 2, 4, 23, 46, 92
The only factor that all four numbers have in common is 1, so 1 is the GCF.
39 and 45's highest common factor is three.
The GCF of 6, 39, and 45 is 3.
56
3
The GCF is 3.
The GCF is 3.
The GCF is 3.
The answer to this problem is simple, the Greatest Common Factor (GCF) is 27.
The GCF is 3.
The greatest common factor of 45 and 175 is 5.
The greatest common factor of 45 and 225 is 15.The GCF is: 45
The greatest common factor of 135 , 225 , 45 = 45
